DES-3800:4#
config scheduling
Purpose Used to configure the traffic scheduling mechanism for each COS queue.
Syntax config scheduling <class_id 0-7> {max_packet <value 0-15>}
Description The Switch contains 8 hardware priority queues. Incoming packets must be mapped
to one of these four queues. This command is used to specify the rotation by which
these four hardware priority queues are emptied.
The Switch's default (if the config scheduling command is not used, or if the config
scheduling command is entered with the max_packet set to 0) is to empty the
hardware priority queues in order − from the highest priority queue (hardware queue
7) to the lowest priority queue (hardware queue 0). Each hardware queue will
transmit all of the packets in its buffer before allowing the next lower priority queue to
transmit its packets. When the lowest hardware priority queue has finished
transmitting all of its packets, the highest hardware priority queue can again transmit
any packets it may have received.
The max_packets parameter allows you to specify the maximum number of packets
a given hardware priority queue can transmit before allowing the next lowest
hardware priority queue to begin transmitting its packets. A value between 0 and 15
can be specified. For example, if a value of 3 is specified, then the highest hardware
priority queue (number 3) will be allowed to transmit 3 packets − then the next lowest
hardware priority queue (number 2) will be allowed to transmit 3 packets, and so on,
until all of the queues have transmitted 3 packets. The process will then repeat.
Parameters <class_id 0-7> − This specifies which of the four hardware priority queues the config
scheduling command will apply to. The four hardware priority queues are identified
by number − from 0 to 3 − with the 0 queue being the lowest priority.
max_packet <value 0-15> − Specifies the maximum number of packets the above
specified hardware priority queue will be allowed to transmit before allowing the next
lowest priority queue to transmit its packets. `A value between 0 and 15 can be
specified.
Restrictions Only administrator-level users can issue this command.
